hey, what’s that in your drink?

Nordic Rock is mined from ancient Swedish pollution-free base rock. It is the purest way of cooling your drink – literally ‘on the rocks’. Stone does not melt, which means no unclean water in your glass. They are also reusable making them very eco-friendly. To use, simply place the stone ice cubes in the freezer for approximately one hour before use. For a normal glass, two or three Nordic Rocks will be fine. They give off their cold gradually and equally.Nordic Rock: Stone Ice Cubes

Did you read what you wrote? All that is just marketing BS.
“ancient Swedish pollution-free base rock” – Base rock is ancient, in fact it’s beyond ancient
“Stone does not melt, which means no unclean water in your glass.” – And how are you planning to storage them clean?
“eco-friendly” – as mining and transportation from Sweden always is… (and cleansing by the way)
Love swissmiss but come-on.
